Introdução

Use this guide to safely remove the glued-in battery from your MacBook Pro with the help of an iFixit battery replacement kit. The adhesive remover in your kit will dissolve the adhesive securing the battery, allowing you to remove it with ease.

Apple issued a battery recall for this model in June of 2019—so before replacing your battery, you can check to see if you are eligible to receive a replacement for free from Apple.

iFixit adhesive remover is highly flammable. Perform this procedure in a well-ventilated area. Do not smoke or work near an open flame during this procedure.

To minimize risk of damage, turn on your MacBook and allow the battery to fully discharge before starting this procedure. A charged lithium-ion battery can create a dangerous and uncontrollable fire if accidentally punctured. If your battery is swollen, take extra precautions.

Note: The solvent used to dissolve the battery adhesive can damage your speakers if it comes in contact with the plastic speaker enclosures. Therefore, this guide instructs you to remove the speakers before proceeding to the battery. Removing the speakers requires also removing several other components including the logic board.

    • Remove the following P5 pentalobe screws securing the lower case to the MacBook Pro:

    Just to add to my comment above (I can't edit it because it's anonymous), my MacBook Pro is a mid-2015 15in model 2.8GHz (A1398; EMC2881). For the bottom case it uses six 3.1mm screws, and four 2.3mm screws at the clutch/hinge side of the MacBook Pro. I tried using a 3.1mm screw at the clutch/hinge end, as described in the main article, and they don't fit. It has to be four 2.3mm screws.

    WAIT!.. STOP.

    iFixit has had a slew of defective batteries that they will require you take out and return (after gluing them in). Search on: "Battery percentage suddenly drops" here on this site. This process is 50 steps to get the new battery in, and another 50 to put all the parts back. For $199, Apple will do the whole repair, warranty it, and also replace the trackpad and the keyboard (because it's easier for THEM to do).

    Ifixit WILL NOT stand behind defective batteries unless you spend another 4-6 hours swapping in a new one. NOT. WORTH. IT. See posts here (Battery percentage suddenly drops from ~60% to 7%) on frustrated customer’s multiple attempts and class-action lawsuits.

    Thank you for this info, you’ve probably saved a lot of time, and hassle (myself included, if I end up going through with this repair).

    Andrew Poindexter -

    The instructions below have you basically taking ALL of the guts out of case. I’ve been doing my own apple repairs since before ifixit was a thing and this one is a handful. My battery was swelling and I wanted to remove it before it burst or bent the case so I took it out without having a replacement and it occurs to me that aside from using the solvent (liquid) to remove the adhesive, you could probably do this only taking the trackpad ribbon out. I have mine reassembled now and will research the best battery to buy but I think installation will take about 5 minutes. See if you can slip a plastic gift card under the battery and wag/saw the adhesive out without the solvent before you go through all of this. It might work. Note, don’t bend or put too much stress on the battery and certainly don’t puncture it…

    I’m having a problem trying to get the screws off. I have a set of pentalobe screwdriver set. I found one screwdriver that fits perfectly on one set of screws, but I am unable to unscrew it. I tried using some force pushing the screwdriver into the screw, but nothing happens. Any suggestions?

    henry_k_wong - Responder

    All the screws on mine are the same length for some reason.

    ccfman2004 - Responder

    I would recommend the first step is: Run the battery down to ZERO before doing any next step. This reduces risk to you, people nearby, to the MBP and greatly reduces the risk of fire. Step 2 should be: Double-check that the battery is at zero.

    I like others listed below and on YouTube, disagree with these full tear down 70+ steps being the only focus. I get that I have to be careful not to get the acetone solvent near the speakers. I skipped 25+ steps by: tilting the MBP away from the speakers and using very little acetone solvent. More pressure with the plastic cards and only a few drops of solvent. While giving the full set of instructions is fine it should be very clear that you can (at the user’s own risk) do this.

    The trick to putting it back on is to guide your fingers to the same level as the clips, and then when you put the case down move your hand from the left side of the case to the right side of the case; applying pressure when you reach the area where the clips are.

    @lawrencetaylor On any electronics repair, you need to disconnect all sources of power before you start. It’s a basic safety precaution and also removes the risk of accidentally shorting a connection somewhere (which can potentially kill your MacBook).

    Guys, be very carefull with these 3 cables.. If you are not going to replace the whole display, just be careful as much as possible.

    Adi - Responder

    When reconnecting these tiny wires, use one hand to guide and align the connector by holding the wire and the other hand to press them down with a flat end of a spudger. Spent 10 minutes figuring it out and connecting the first one, then only a few seconds on both of the remaining connectors :)

    If you try to do this with one hand, it’s extremely easy to move them out of the alignment while pressing them down.

    Aivar Kavshevich - Responder

    I think there is a better way - where you disconnect the wifi card using the black screw in middle of wire 2 and 3 first and then untie these connectors. I pryed away the connectors but the sockets on the card were all damaged during the process. Ended up having to get a replacement card before reassembly could be completed. So again there are 2 components - connectors which are being pryed away and really fine and delicate socket. Very easy to damage them. Better to take the card off and delicately peel these connectors off. I would not recommend using these pry sticks mentioned here for that.

    ATTENTION ! Cette étape est grandement sous-estimée, aucune mention de la délicatesse de l’opération contrairement à d’autres étapes bien plus facile… De plus, il semble possible de sauter cette étape en déconnectant seulement la carte comme expliquer sur la version anglophone du guide !!!

    I highly suggest against disconnecting these wires. It's very likely that you will damage either sockets or wires. Do as others recommend, just remove the network card. Prying tool is not good for this step. I broke 1 out of 3 sockets. I wish I read all the comments before operating. Now I gotta get another card :(

    Just finished replacing both speakers using this guide. VERY good. I did not remove the individual wires - just removed the card with wires attached. Seemed to be the safer, easier way to go.

    Can anyone explain how to remove the card instead of wires? About to try that out instead, but am going in blind! I see the screw holding the card down, just not sure what to do next…

    Peter Scalzitti IV - Responder

    This is one of those skills that you get experience right after you need it.

    I learned these connectors doing RF work. They require a deft touch. Put slight downward pressure while you work to align the pair. Once you get the hang of it, you will know when they are aligned, and they will go back together with a light push and make a slight snap.

    If they don’t immediately pop together with a light push, they’re not aligned quite right. Don’t force them, they have a very limited number of make/break cycles.

    The cables should retain their bent shape well enough to show where each goes. One it too short to go too far off, and one is too long to fit to the nearest connection.

    Malcolm Hall - Responder

    All connectors are incredibly fragile. I damaged the fan connector locking latch just by trying to lock it back in place. Fortunately the cable, by the way it inserts, it’s being pushed in rather than pulled on, however, I do have concerns with it not making a proper connection. Malcolm, I am wondering how you fixed your damaged connector?

    Robert Habib - Responder

    The connector slides into the socket so using the flat end of the Splunger under the cable and gently lifting draws the connector apart.

    Dennis Newton - Responder

    This step is unnecessary if you are only replacing the right speaker. - simply loosen the cables that run across the fan, and you will later be able to remove the fan without disconnecting this cable. If you are replacing the left speaker, you do need to remove it, as otherwise the cable will be in the way when you lift out the logic board.

    Adding to the other comments, the fan is very light and has no resistance lifting out of the place it sits in.

    I carefully lifted the fan just before there was any tension on the cable.

    With the fan held in my right hand and spudger in my left, I moved the spudger under the fan approaching from the left side.

    This allowed me to easily place the flat end of the spudger under the cable where the thicker plastic sits and gently pry the cable up until the cable broke away from the body.

    I then used the pointed part of the spudger to gently pry the connector part of the cable away from the socket while gently pulling the fan away until the cable was disconnected and the entire fan was free.

    All connectors are incredibly fragile. I didn’t have any problem unlocking the cable but rather after finishing the job and closing the hinged retaining flap. The hinged flap wiggles, it moves and wasn’t 100% properly aligned. It’s not like it was badly out of place and I tried to force it, no, on the contrary, I was being extremely delicate, but it wiggles in place so so very slightly since it’s not a real hinge. You need to make sure it hasn’t moved before applying any pressure trying to close it or IT WILL break off. It’s frustrating that I damaged the fan connector, not by prying on the socket, but in the last step of just locking the latch.

    Fortunately the cable, by the way it inserts, it’s being pushed in rather than pulled on, however, I do have concerns with it maybe not making a proper connection. I am now wondering how other’s have fixed your damaged connectors? As I mentioned at the beginning, I’m sure I’m not the first since all the connectors are incredibly fragile. Any feedback?

  39. Pull the display data cable straight out of its socket on the logic board. Do not lift up on the display data cable, as its socket is very fragile.

    • Gently bend the display data cable toward the display hinge, to expose the screws on the MagSafe 2 board.

    The wording of the instruction: “Pull the display data cable STRAIGHT OUT of its socket on the logic board” could lead to errors. It almost happened to me.

    Instead you should word it: “Pull the display data cable parallel to the face of the logic board being careful to keep it straight and NOT LIFT UP on the cable”.

    I realize you mention it later in the warning immediately below, however, by first saying “pull the cable straight out” leads to confusion and could lead the user to attempt to interpret “PULL STRAIGHT OUT” as “PULL UP” unsuccesfully only to later notice, maybe after breaking it, that there was a warning.

    Wording it properly the first time will make the warning unnecessary.

    I had the same thought as I almost proceeded without noticing the red text warning.

    I especially think the second warning about not touching the contacts on the data connectors should be listed before the instructions on removing it.

    Agree with Robert. Suggest “SLIDE the display cable to the right, out of its socket…” would be less misleading.

    prreitz - Responder

    I think it bears repeating just how fragile this connector is, particularly on reinsertion. The problem isn’t just technicians touching the connector end; you can damage the pins simply by inserting it slightly out of alignment, or at an angle, because the outermost pins are VERY close to the edge and are very fragile. They have the appearance of being embedded in the connector but they’re actually spring traces just lying on top of it. I managed to bend the southmost pin upwards reinserting it; luckily it flattened out again and worked, but if it had not been possible to do that it’d have been a whole new screen assembly.

    Is there a reason I should adhere the new batteries? I’d opt to leave them detached, if I can. The primary concern is obviously internal movement causing premature wear on the battery cables.

    Ok, studied all of the comments and other videos on Youtube. Dove in last night. But I didn’t remove the logic board. I just used braided string to shimmy down each battery to separate it from the glue backing. That worked great. When putting in the new battery, I made sure that its connector was connected to the laptop, then removed the backing and placed the new battery in place. Laptop powered up, and is now charging. And keep in mind, I paid a little extra for the tools and cards and shims, they were all very helpful. If you are trying to remove a screw you don’t have a tip for, you shouldn’t be removing it. :)

    It would’ve been helpful to include a list of instructions for replacing all of the parts instead of just making us read the instructions backwards. When I was putting the logic board back on, I didn’t realize that one of the connectors got stuck underneath the board when placing it back into the computer. After reconnecting half of the connectors I realized one of them was stuck underneath so I had to disconnect all of the ones I reconnected to lift the logic board back up and pull out the connecter that got stuck underneath. I forgot to detach the keyboard backlight connecter and when I lifted to logic board the pull out the connecter stuck underneath, I snapped the keyboard backlight cable that was still attached. Luckily this isn’t a major component and I don’t really use the keyboard backlight that much anyway, but if you included a list of instructions for reattaching everything I probably wouldn’t have had this problem.

    the plastic credit cards work fine if you wedge them in the corners to start gently - but firmly leveraging / shimmying your way under.

    However, I was lucky, the batteries came out quite easily (don’t be afraid of the sound of tearing adhesive tape) and some people might have super stuck batteries and need to use the liquid - which then means you have to protect everything from the acetone in case it leaks onto circuitry.

    Thanks Tycho, you saved me a world of anguish disassembling the whole contraption. firm, gentle and patient worked fine without liquid for me.

    Good luck all you fixers !!!

    I have an additional suggestion on placing the new battery. With the laptop case hinge away from you, I put a piece of masking tape from the bottom (closer) right corner of the new battery pack to the bottom left corner of the battery pack with some slack in it. This allows you to pick up the bottom edge of the batteries in an arc, and position and place the center ones first. I screwed in the battery controller, pulled the heavy plastic backing off of the batteries, then placed the center batteries, followed by the outside ones. be careful to stick the tape firmly. The last thing you want is the batteries coming free and falling to the case and sticking wherever they land. Good luck. This was the most stressful step for me. While you’re reassembling, give the fans and the fins of the heat exchangers a good dust with canned air. :)

    The protective film covering the adhesive is one long strip that keeps the batteries aligned. It’s kind of stiff and part of it sticks out preventing the center batteries from aligning properly, so I couldn’t really check the fit. Once I pulled off the film, the left and right batteries became difficult to manage and I ended up dropping a couple prematurely. In hindsight, I think it would have been helpful to cut the film between the cells and cut out the part that was in the way first.

    This was quite easy. Follow the sequence. I took a 50cm long wide tape where I put the screws head down on in order to have them in the right sequence while assembling the machine again. Timeframe was 1.5 hours.

    All in all this was a great kit. The worst part is step 6. Pulling the 3 little wires off the airport card. Honestly, I would probably just take the entire card off vs those three wires… With respect to putting the new battery in, line up the two screw holes in the battery chips with the case. I also installed the speakers first just to make sure that I’d get the placement right. Other than that, there are a lot of ribbon cables so be meticulous and take it slow. This took about 3 hours to break everything down and about half an hour to put everything back together. Good luck!

    Like many others here; I did not do all the steps. I would have surely broken something else. Once I (carefully) disconnected the battery and track pad ribbon cable and carefully moved them aside, I then applied the solution to the batteries to loosen the adhesive. Put my Macbook Pro on a slant to keep the solution from running everywhere, btw. Then I used dental floss to cut thru the adhesive. Didn’t have to work at it much because my batteries had swelled to the point where they had mostly dislodged themself from the adhesive. Great kit and loved that iFixit did not skimp on the tools and accessories. What a difference a new battery makes!!! After charging it and then draining it (calibrating) it seemed like it took forever for the battery to drain. Thanks iFixit!

Do I need to remove all these things just to replace the battery or can I just remove the connectors above the battery than the battery?

Tony - Responder

I just went through this process yesterday, and today wondered why I needed to take all that crap out, because I don’t remember anything blocking the battery removal, that would require removing the speakers, logic board, etc. I think it’s because of the acetone adhesive solvent. It’s powerful stuff that can easily damage the system. Maybe, if you are able to get the battery out without the solvent, you can skip all the other stuff. I will say, however, that in my system, it seemed like the adhesive is real solid. It felt like I was pressing the card up against aluminum studs in the frame, until the solvent loosened it up. If you try to remove the battery without the solvent, be very careful not to use excessive force and warp your frame.

I made it within 1 hour doing Steps 1-5, then Steps 46-50.

I removed battery heating the aluminium frame in the location of battery pack on the opposite side of the frame with NTE HG-300D Mini Heat Gun, and then gently peeling this battery pack with plastic spudger. You may need to reheat the area several times.

For 2 central battery elements you can't heat aluminium frame because they are below touchpad, so I peeled batteries a little bit with spudger, heated the underneath gently, and then peeled it again. Also dental floss could help cutting the glue underneath the battery.

Thanks for your fast approach, worked fine for me as well! I did not use any glue dissolver at all.

Tom Vandepoel -

Same for me, about an hour. I didn’t use a heat gun, just finagled the tip of the adhesive dissolver around the edges and otherwise followed the directions using the plastic cards. That dissolver is great stuff, worked twice as fast as the instructions.

Bob Compono -

Thanks for posting your short version. I did mine in about an hour with dental floss and the plastic cards. No heat. No solvent.

So glad I read the comments before going down the path of insanity.

I followed your comment to skip most of the steps and just remove the keyboard cable and the batteries. The replacement of batteries revived my water damaged MacBook Pro which stucked in boot loop.

In the beginning I tried to avoid “finagled“ situation thus only dripped a drop or 2 of dissolver each time. I also use a thin tip to induct the dissolver into the gap. But it’s very hard to do the flossing work and very slow. For the last 2 centr
